WOVEN PILE FABRIC.

SPECIFICATION forming part of Letters Patent No. 442,749, dated December16, 1890.

Application filed December 12, 1889. Serial No. 333,404. (No model.)

To all whom it may concern:

Be it known that I, JOS REIXACH, manager, a subject of the Queen ofGreat Britain, residing at Manningham Mills, Bradford, in the county ofYork, England, have invented certain new and useful Improvements inlVoven Pile Fabrics, of which the following is a speciiication.

lWIy invention relates to that class of pile fabrics woven face to facein which the pile is tied with one pick only, and its object is moreeifectually to hold the pile into the fabric. I do this by means ofextra or additional warps in each ground or cloth of the double fabric,one for each pile warp used, and which, whenever a pile warp is tied inis made to float on the back of the cloth and ride over the back of thepile warp, and so to cover or fix the back of the pile-threads andprevent them from being rubbed at the back and drawn out backward, orfrom being pushed back by pressure applied to the face of the pile.

Velvets are now generally made with the pile tied with one pick only,thus using much less'pile 'warp than when the pile warp has to go roundthree or four picks, as it used to do in the old pile fabrics, while atthe same time a finer-faced cloth is obtained. Then a stilf ber, likemohair, wool, tbc., is used for the pile warp, if pressure is put on theface of the pile, the loops of pile-thread are pressed through the clothand form loops on the back, and these, when subjected to wear, getgradually drawn out entirely from the cloth and the fabric is spoiled.

By myimprovements I prevent the pile from being so pressed back anddrawn out, and thereby not only attain the advantages desired 'fromtying in the pile by one pick only,

but also by the employment of the extra or additional floating warp Imake such fabrics as marketable and durable as the old-time fabrics.

The accompanying drawings show my improvements applied to a double pilefabric, woven, as described in the specification of British patentgranted to me and to S. C. Lister, as No.18,794, of 1888. In this fabriceach loop of pile warp where it is held into one or the other of thecloths by a single pick of weft is heldbetween two ground-warps abovethe weft, and also between two ground-warps below the weft, so that theends of the loop of pile are-held erect.V

In the accompanying drawings, Figure 1 is a diagram showing the back ofone of the cloths of a double pile fabric, made as heretofore, and asdescribed in the specification of the British patent above mentioned.Fig. 2 is a similar diagram of the corresponding parts of my improvedfabric. Fig. 3 isadiagrammatic cross-section through my improved doublepile fabric; and Fig. 4, a similar view of one-half of my improvedfabric, showing the relation of its parts after the pile connecting thetwo cloths has been severed.

The pile warps a are shown as caught first into one cloth and then intothe other. They are in two sets or divisions, so that one-half of themmay be tied into each cloth by one weft-thread c. Then the other set ordivision tied in the same cloth by the third of these weft-threads, andnone tied in by the fourth, and so on. One of the pile warps a is shownin full, the other in dotted lines. t

The two sets of ground-warps ZI which form each cloth are shown as madeto cross after every two picks thrown between them. The additional warpsd (shown in dotted lines) are made to ioat over the backs of thepile-loops, and each additional warp is tied in at every fourth pick ofweft put into the cloth, and is made to iioat at the back over threewefts cviz., the weft which ties the pile and the two wefts which comebefore and after this weft.

It will be observed that the loops of pile a are tied into the ground bya single pick of weft c, and are held between two groundwarps b abovethe weft and two similar warps b below .the weft, as clearly shown inFigs. 3

and 4.

The different igures of the drawings, as above stated, are diagrammatic,showing the manner of weaving the several threads.

In Figs. 3 and 4 the lower warp-threads are shown as arranged below theinner ends of the pile-loops; but in the finished fabric the loops ofpile are held between two groundwarps above the weft and two .othergroundwarps below the weft.

What I claim herein as new and as of my my own invention is- IOO l. Adouble pile fabric in each of the two cloths of Which the loops of pileare tied into the ground by t single pick of weft only, and in Which thebacks of the pile loops are covered by a ground-Warp floated over them,substantially as described.

2. A double-pile fabric in each of the two cloths of Which the loops ofpile are tied into the ground by a single pick of Weftfare held betweentwo ground-warps above the Weft and tWo other ground-warps below theweft, and the backs of the pile-loops are covered by a ground-Warpoztted over them, substantially as described.

3. A pile fabric in which the loops of pile 15 are tied into the groundby a single pick of weft only, and in which the backs ofthe pileloopsare covered by a ground-Warp floated over them, substantially asdescribed.
